The definition of compassion that most accurately reflects what I’ve learned from the research is from American Buddhist nun Pema Chödrön. In her book The Places That Scare You, Chödrön writes: When we practice generating compassion, we can expect to experience our fear of pain. Compassion practice is daring. It involves learning to relax and allow ourselves to move gently toward what scares us….In cultivating compassion we draw from the wholeness of our experience — our suffering, our empathy, as well as our cruelty and terror. It has to be this way. Compassion is not a relationship between the healer and the wounded. It’s a relationship between equals. Only when we know our own darkness well can we be present with the darkness of others. Compassion becomes real when we recognize our shared humanity.

It is utterly and irrevocably possible to empty all hurts and, therefore, to love, to have compassion. To have compassion means to have passion for all things, not just between two people, but for all human beings, for all things of the earth, the animals, the trees, everything the earth contains. When we have such compassion we will not despoil the earth as we are doing now, and we will have no wars.

Compassion, regardless of one’s status or position, is the treasure within every person’s mind. The Venerable Master said, “One can be without anything, but never without compassion.” Compassion is giving others joy and alleviating their suffering. If a person can always embrace compassion and uphold kind thoughts, then naturally there will be less troubles and worries in live.

Compassion is not a demand on others, nor is it a standard by which we judge people. It is a way to discipline ourselves. Compassion does not mean blind tolerance to physical attack or verbal abuse. When justice is threatened or when good people are being slandered or attacked, we should stand up bravely for them. Compassion is not a momentary emotion, but a persistent service for others. Compassion is not just being kind only to our friends and family, nor does it mean we are to expect anything in return. Compassion is not always about praises and encouragement. Sometimes, in the interest of common well-being or to subdue the hard-headed, an angry expression is required to subdue villains. This is actually the greatest and most difficult form of compassion.

Through compassion it is possible to recognize that the craving for love that people feel resides also in our own hearts, that the cruelty the world knows all too well is also rooted in our own impulses. Through compassion we also sense our hope for forgiveness in our friends' eyes and our hatred in their bitter mouths. When they kill, we know that we could have done it; when they give life, we know that we can do the same. For a compassionate person nothing human is alien: no joy and no sorrow, no way of living and no way of dying.

How can one be compassionate if you belong to any religion, follow any guru, believe in something, believe in your scriptures, and so on, attached to a conclusion? When you accept your guru, you have come to a conclusion, or when you strongly believe in god or in a saviour, this or that, can there be compassion? You may do social work, help the poor out of pity, out of sympathy, out of charity, but is all that love and compassion?

What is compassion? Compassionate are those who can put themselves in other people’s shoes.

The experience of compassion is complete abandonment of the inclination to resist emotional discomfort. It’s full acceptance: of the person, of the pain, and of our own reactions to the pain.

Having compassion starts and ends with having compassion for all those unwanted parts of ourselves, all those imperfections that we don’t even want to look at. Compassion isn’t some kind of self-improvement project or ideal that we’re trying to live up too.

Compassion asks us to go where it hurts, to enter into the places of pain, to share in brokenness, fear, confusion, and anguish. Compassion challenges us to cry out with those in misery, to mourn with those who are lonely, to weep with those in tears. Compassion requires us to be weak with the weak, vulnerable with the vulnerable, and powerless with the powerless. Compassion means full immersion in the condition of being human.

to have compassion (co-feeling) means not only to be able to live with other's misfortune but also to feel with him any emotion -joy , anxiety, happiness, pain

Compassion is the sometimes fatal capacity for feeling what it is like to live inside somebody else's skin. It's the knowledge that there can never really be any peace and joy for me until there is peace and joy finally for you too.

"Compassion dervies from the Latin patiri and the Greek pathein, meaning "to suffer, undergo or experience." So "compassion" means "to endure [something] with another person," to put ourselves in somebody else's shoes, to feel her pain as though it were our own, and to enter generously into his point of view. That is why our hearts, discover what gives us pain, and then refuse, under any circumstance whatsoever, to inflict that pain on anybody else. Compassion can be defined, therefore, as an attitude of principled, consistent altruism."

What does it mean to be compassionate? Not merely verbally, but actually to be compassionate? Is compassion a matter of habit, of thought, a matter of the mechanical repetition of being kind, polite, gentle, tender? Can the mind which is caught in the activity of thought with its conditioning, its mechanical repetition, be compassionate at all? It can talk about it, it can encourage social reform, be kind to the poor heathen and so on; but is that compassion? When thought dictates, when thought is active, can there be any place for compassion? Compassion being action without motive, without self-interest, without any sense of fear, without any sense of pleasure.
